Hi @Rastateach! This can be fine tuned through your motion settings. Battery powered Doorbells will have settings such as motion frequency and recording length, which are meant to preserve battery. Please ensure these settings are not interfering with recordings and back to back captures.
If a motion was recently detected and logged in your event history just before the delivery, motion frequency setting might space out time between the next motion events. If you have stairs leading up to your entryway, many neighbors have found success with our Wedge Kits, which can be found on our accessories page at Ring.com. I hope this helps!
